Waveguide Head-Up Displays

Head-up displays have brought forth a series of fresh challenges for optical designers. VirtualLab Fusion, with its fast physical optics approach, offers the necessary tools to undertake the modelling and design of such devices;

  • ray and physical optics simulations with 
  • both sequential and non-sequential tracing (characterized by easy switching between the two modes)
  • advanced PSF/MTF calculation
  • rigorous model to calculate efficiencies of diffraction orders

are just some of the characteristics that underpin the potential of VirtualLab Fusion when it comes to the modeling and design of head-up displays.
